He looked up and smiled at Forsythia.

"It's okay, maybe we'll pass by the city you mentioned on this patrol, and you might be able to remember it then."

Lu Juan's comfort was obviously more effective, and Forsythia nodded heavily, happy again.

"Actually, it's not hopeless now, at least we know that this kind of lock is owned by aliens, and there is an underground black market for aliens in the city, so we can try our luck." Li Yuan chuckled.

The hour had passed, and there was almost no one on the streets.

There was only one shop on the entire street with its lights on.

The three of them stood in the doorway, their faces covered with masks.

Li Yuan and Lu Juan glanced at each other.

Knock on the door three times, then knock again every few seconds.

The door was slowly opened, revealing a somewhat withered face, an old woman with gray hair, whose face had been left by the years.

"It's so late, is there something wrong?" The old woman's voice was very soft and a little hoarse.

Li Yuan took out an ink-colored stone from his sleeve and carved a special symbol on it.

"The cold mountains are like the sea." Hand the stone in your hand to the old woman.

The old woman paused, did not take it immediately, and her eyes suddenly became sharp.

"Where did you come from?" The eyelids and the corners of her mouth drooped down at the same time, only to find that her face looked a little fierce without smiling.

But Li Yuan didn't have the slightest fear on his face.

"You've trespassed."

His voice was calm, without emotional fluctuations, but it made the old woman's face change greatly, reached out to open the door, and then bowed down her waist, which was almost straight.

"Childe, please come in."

Lu Wan was a little suspicious in his eyes, and followed Forsythia in, and Forsythia's relaxed appearance was obviously not the first time he came.

The old woman glanced at the street outside and made sure that no one had closed the door.

Li Yuan, they stood in the house and waited.

Five lights were lit in the house, and Li Yuan's eyes flashed.

The old woman closed the door, then walked to the altar, twisted the candlestick on the altar, twisted it to the end, and then heard a "click".

The floor tiles under the offering table were lifted up, and then automatically rotated, and the wall that was originally next to the offering table suddenly bounced open, and this wall turned out to be fake.

The old woman stepped forward and pulled away, revealing the stone steps that snake down inside.

The old woman turned around and made a special salute to Li Yuan, then took a half step back and made way of the way.

Li Yuan bowed slightly, and then walked straight in.

Luwan and Forsythia followed him.

After the three of them entered, the old woman closed the door, and there was another "click", and then the table was automatically restored.

The fire box in Li Yuan's hand flickered, and the stone steps were dark and long, and the height was uneven.

Fortunately, Lu Juan's night vision ability is very strong, otherwise you really have to be careful, otherwise you will fall down, and I don't know if you will die.

"Be careful, this isn't the entrance to the alien black market in the city, so there are no wall candles on this road." Li Yuan explained to Lu Xuan.

Lu Wan's eyes moved slightly.

"That's why the old woman suddenly changed her face after you said the code just now."

"Yes."

Since it is not the entrance to the black market of the alien race, they say the secret language, and the old woman will be more cautious, because it means that they are not from the city.

And it's not impossible for outsiders to go to the interracial black market, but they have to check their identity after all.

"Then why did that old woman let us in again?" Lu Wan wondered.

Li Yuan said that you have transgressed, and the old woman suddenly changed her face, what kind of rule is this?
